Zusammenfassung:	A media roll holder assembly (20) for a roll (R1) that is detachably supported in a printing system (1). A rotational drive (55) comprising a roll engaging element (56) configured for fittingly engaging and driving a drive engaging element (83) of a roller (R1), for example an Oldham coupling. A first guide surface (51) is configured to support and direct the roller (R1) in a loading direction. A second guide surface (60) at least partially extends at an angle with respect to the first guide surface (51), such that movement of the roller (R1) over the first guide surface (51) brings the drive engaging element (83) in contact with the second guide surface (60). The second guide surface (60) directs the drive engaging element (83) into a predetermined orientation, which orientation aligns the drive engaging element (83) with the roll engaging element (56) in a loading orientation, such that further movement of the roller (R1) in the loading direction inserts the drive engaging element (83) into the roll engaging element (56).
